While pg_dump has included dependency information in archive-format output ever since 7.3, it never made any large effort to ensure that that information was actually useful. In particular, in common situations where dependency chains include objects that aren't separately emitted in the dump, the dependencies shown for objects that were emitted would reference the dump IDs of these un-dumped objects, leaving no clue about which other objects the visible objects indirectly depend on. So far, parallel pg_restore has managed to avoid tripping over this misfeature, but only by dint of some crude hacks like not trusting dependency information in the pre-data section of the archive. It seems prudent to do something about this before it rises up to bite us, so instead of emitting the "raw" dependencies of each dumped object, recursively search for its actual dependencies among the subset of objects that are being dumped. Back-patch to 9.2, since that code hasn't yet diverged materially from HEAD. At some point we might need to back-patch further, but right now there are no known cases where this is actively necessary. (The one known case, bug #6699, is fixed in a different way by my previous patch.) Since this patch depends on 9.2 changes that made TOC entries be marked before output commences as to whether they'll be dumped, back-patching further would require additional surgery; and as of now there's no evidence that it's worth the risk. |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Changes between all PostgreSQL releases are recorded in the file HISTORY. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
